Web1 aug. 2015 · Optical proximity correction (OPC) is the first step in this process. Various ways have been developed for efficient creation of accurate process window aware OPC models. Also, the use of the actual OPC step, to transform the target patterns into actual lithography mask patterns has seen significant progress. Webapplied to lithographic images. First of all, the metric is only defined for equal lines and spaces. Although it is possible to modify the definition of image contrast to apply, for example, to an isolated line or to a contact hole, it is not clear that these modified definitions are useful or comparable to each other.
